Patented Feb. 25, 1936 Umso STATES PATENT OFFICE 3 Claims.

The invention relates generically to a shingle, shingle outer walls and roof constructions.

An object of the invention is to provide a composite 4construction which may be constructed of a suitable sheet roofing material such as prepared roofing as ordinarily made which may be impregnated or coated with a waterproof substance such as asphalt or the like, as a felted foundation layer. The foundation layer is provided to receive the hooked-shaped end of the plates placed there above and thereon, as well as the hooked-shaped end of the cooperating strips that are superimposed upon the plates, the plates and strips being anchored ,thereto and therewith.

A further object of the invention is to provide an improved shingle construction with an improved dam running transverse thereof, the dam on the plates and the dam on the strips being so formed that they iit with ndelity. The strip may be telescopically adjusted in relation to the plates.

A further object of the invention is to provide a felted foundation layer of such exibility that it will yield to slight inequalities when projected over the dam. The flexibility of the edge of the base over the bead tends to permit the contacting surfaces to overcome any slight unevenness in the contacting .surfaces and thereby permit satisfactory contact throughout the length of the transverse dam, when assembled. The unevenness is therefore neutralized to as great an extent as possible.

The foundation felt at this juncture, therefore seals the dam against water and wind, acts as a leveling, and lastly as a cushioning means to dissipate any slight vibration between the cooperating elements.

It has been :found of special advantage that the construction according tothe invention works well when it becomes necessary to out a plate in meeting the exigencies of use in assembly, for the reason that the raw and unsightly edge may be painted with asphaltum or other suitable paint and then placed under a strip where it is additionally protected from oxidation. I

It is also an object of the invention to provide the strip on its under side with a pad of asphalt or other suitable impregnated or coated substance having adhesive qualities to act as a deadener, a leveling means, a cushion and a seal, and

` further as a means to prevent the vitreous enamoi. 10s-17) However the roof may be constituted of other than enameled plates and strips if desired. Further objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the accompanying drawings and finally pointed out in the claims.

Referring to the drawings:

Figure 1 is a fragmentary plan view of a roof constructed in accordance with the invention, showing the assemblage of the strips, plates and base.

Figure 2 is an end view oi Figure l showing the strip bridging the joint between two plates, and a plate superimposed upon the strip, the plates being notched to facilitate receiving the hookedshaped end of the strip and the notch in the plate receiving a flat portion of the plate.

Figure 3 is a sectional view of Figure l, and showing the dam on the plate, also the dam on the strip, and the dam on the strip fitting over the dam on the plate, also the base, and the deadener upon the strip.

Figure 4 is an isometric view of the strip, showing the hook on the strip, the dam, and the deadener.

Figure 5 is an isometric View of the plate showing the notches in butt and the flanges thereon.

The same part is designated by the same reference character wherever it occurs throughout the several views.

In accordance with my invention, I employ a base or felted foundation layer i@ of suitable sheet roofing material which may be impregnated or coated with a waterproof substance, such as asphaltum. This felted foundation layer may also be made of a series of sections of ample length laid end to end rather than a continuous strip if desired. The felted strip must be pliable, and easily deformed, and also have the property of owing slightly under pressure.

Mounted on this foundation layer there is positioned a plurality of plates i l, ii, glass enameled or otherwise. The plate is provided with a hooked-shaped butt i2.

The plate is a preformed one-piece plate of metal enameled or otherwise, having a downward extending 'flange i3, and a backward extending ange it, formed integrally therewith.v 'Ihe flange i3 is provided with a plurality of notches i5, i5, adapted to receive portions of a strip element hereinafter described. The ange lll has removed from it sections equal to the length Fig. 2. One half of the receiving notch is formed at the contiguous end of each plate.. The notch is made slightly longer than the width ofthe strip to facilitate slight adjustment in assembly. The strip is also provided with a bead or dam 22 intermediate its length and running transversely thereof. This bead or dam is preformed to t over the bead or dam l1 with fidelity so that when the plates are positioned, there is provided across the plates and the strips a continuous bead Aor dam.

The under side of the strip is provided with a felted deadener 21 impregnated with asphaltum or the like. Liquid asphaltum may be sprayed on the strip to keep the production cost down to a minimum. This pad on the strip has several distinct functions, nrst as a deadener of sound between the engaging surface of the strips with the plates. second, as a seal between the plate and the strips, and third as a compensating means to assist in levelling the plates when assembled.

The felted base or strips constituting the base IIJ is laid along the eave and secured by nailing on the roof boards throughout its length. Over the base are laid the plates Il, Il. The plates are hooked over the base and properly spaced thereon. The strips I8 are next superimposed over the joints and hooked to the base. It will be noted that the notches provided in butt end o f the plates are of a depth ample to let the short anges I6, I6, slide thereunder without lifting the plates. The plates are nailed to place, the relative place for nailing as shown at 23 in Fig. 3.

The next layer of the felted base is laid so that its lower edge 24 overrides the dam or bead sufficient to receive the hooked-shaped butt of the plates and strips. The dam provides a supporting ledge for the overhanging edge of the base. This construction provides a means whereby the hooks on the plates and strips may be easily hooked to the base. It will be noted that the'upper nat portion 25 of the strip element is received in a notch intermediate the width of the plate as at 26.

The straight continuous darn formed by theA bead on the plates and strips provides an aligning means when positioning the A` 'base relative thereto, for the reason that the overhang of the base can be measured from the bead to the end that overhangs, thus giving the base approximately the same overhang therealong. The overhanging base cooperating with the plates provides a sealing means, Whilst the flexible edge of the base provides leveling means, because it has a tendency to conform to slight irregularities along the crest of the base, and further it acts as a cushion between the underside of the plates and beads or'dam.

Should it become necessary to cut a plate in the assembly of the units in meeting the requirements 0f use, the cut edge may be painted with asphaltum or paint and placed under a strip to additionally protect the cut edge while at the same time the architectural defacement is covered up.

The plates may be made in long lengths and barred with the strip to simulate short plates.

. The strips may be eliminated and the plates as-l sembled in close contact end to end. In all modications the base overrides the dam or bead.

When the roof or Wall is completed and exposed to solar heat, the various contacting felt bases have a tendency to amalgamate and seal the various elements together. f

While I have herein shown and described a preferred arrangement, it will be readily understood by those skilled in the art, that changes and modifications therein may be found desirable or essential in meeting the exigencies of use, and`I desire to be understood as reserving the right to' make any and all such changes or modifications as may be found desirable or essential, in so far as the same may fall within the spirit and scope of the invention as expressed in the accompanying claims. I accordingly desire that the terms of the claims be given the broadest reasonable interpretation, and be limited solely by their expressed terms or by the prior art.
